ResumoData obtained along various segments of the Mid-Ocean Ridge (MOR) are used to construct an idealized model for crustal accretion. The model seeks to predict the topographic, volcanic, tectonic, and hydrothermal characteristics of any given spreading segment of the MOR as a function of distance away from the bounding transform faults. This model is based on a series of detailed mapping efforts carried out on segments of the MOR having a broad range of spreading rates between 2 and 16 cm/yr. This paper includes the results of the French SEARISE program carried out during the summer of 1980 aboard the N/O "Jean Charcot" and two American cruises conducted in 1981 aboard the R/V "Melville".
